Sdo hmi data

HMI is one of three instruments on the Solar Dynamics Observatory; together, the suite of instruments observes the Sun nearly continuously and takes a terabyte of data a day. HMI observes the full solar disk at 6173 Å with a resolution of 1 arcsecond. HMI is a successor to the Michelson Doppler Imager on the Solar and Heliospheric Observatory HMI produces data to determine the interior sources and mechanisms of solar variability and how the physical processes inside the Sun are related to surface magnetic field and activity. It also produces data to enable estimates of the coronal magnetic field for studies of variability in the extended solar atmosphere, which is where the Earth is SDO (Solar Dynamics Observatory) 衛星に搭載されてる3つの観測装置 ( HMI : Helioseismic and Magnetic Imager, AIA : Atmospheric Imaging Assembly, EVE : EUV Variability Experiment) のうち、AIA と HMI のデータ処理過程には共通の部分が多く、合同のデータ処理システムを使っています。. この頁では主に HMI データ取得手順について書いていますが、AIA データ取得の場合もほぼ同じ手順になります。 The Solar Dynamics Observatory, or SDO, images 10 different wavelengths, measured in angstroms (Å), with its Atmospheric Imaging Assembly (AIA) instrument. SDO's Helioseismic and Magnetic Imager (HMI) instrument focuses on the movement and magnetic properties of the sun's surface and provides 3 additional images

50. Analyzing SDO/HMI Data Using Python. Contributed by Monica G. Bobra. Posted on April 24, 2016. Monica G. Bobra. Hansen Experimental Physics Laboratory, Stanford University, Stanford, CA 94305. SDO is six years old now, which means that there is half a solar cycle of data available to study. When SDO launched, most of the solar physics community. Helioseismic and Magnetic Imager (HMI): is one of three instruments aboard the Solar Dynamics Observatory(SDO) designed to study oscillations and the magnetic field at the solar surface. HMI observes the full solar disk a ソーラー・ダイナミクス・オブザーバトリー (Solar Dynamics Observatory, SDO )は、 アメリカ航空宇宙局 (NASA)が打ち上げた 太陽 観測衛星である。. 打ち上げは2010年2月11日に行われ、5年以上にわたる太陽の継続観測を予定している。. この衛星は、Living With a Star (LWS)プログラムの一環である 。 The Solar Dynamics Observatory's (SDO) Helioseismic and Magnetic Imager (HMI) is the first instrument to continuously map the full-disk photospheric vector magnetic field (Schou et al. 2012). Since 2010 May, HMI has mapped the vector magnetic field every 12 minutes 98.44% of the time (Hoeksema et al. 2014 )

<BR /> Aims: The artifacts of SDO/HMI magnetograms that may affect the low-frequency power spectrum of sunspot oscillations are analyzed. <BR /> Methods: Several examples are given that present false (artificial) harmonics, which are produced by Doppler shifts in the power spectra of long-period oscillations of sunspots. This arises from peculiarities in the orbital movements of SDO. <BR. Data from all three SDO instruments (AIA, HMI, and EVE) are used by the NOAA Space Weather Prediction Center. Just this week the NOAA Space Weather Forecast Office started using the SDO EVE data to fill the gaps i SDO HMI Intensitygram image that highlights examples of each tip.

A specific type of artifacts, that originate due to displacement of the image of a moving object along the digital (pixel) matrix of receiver are analyzed in detail. The criteria of appearance and the influence of these artifacts on the study of long-term oscillations of sunspots are deduced. The obtained criteria suggest us methods for reduction or even elimination of these artifacts. It is. The magnetogram from SDO/HMI and the preprocessed result of the raw data are given in Section 3. We then present the extrapolation results for these data including both the raw and preprocessed magnetogram in Section 4
